Why Vehicle Diagnostics Matter: Dash Warning Lights Aren’t Optional
Modern cars are smart. They’re full of sensors and computers designed to monitor performance, emissions, safety systems and overall engine health. When something isn’t right, your dashboard tells you, usually with a symbol you’ve never seen before.
Ignoring a warning light can lead to:
Expensive repairs later
A minor issue, like a misfire or emissions fault, can snowball into serious engine damage if left unchecked.
Safety risks
ABS, airbag and traction control lights aren’t suggestions. These systems help keep you and your passengers safe.
Small issues escalating quickly
Diagnostics can uncover the cause of rough idling, poor fuel economy, loss of power or strange noises.
What your car’s electronics can detect:
- Engine performance issues
- Emission faults
- Transmission errors
- ABS and airbag faults
- Fuel system irregularities
- Overheating and cooling issues
- Electrical problems
- Sensor failures
A diagnostic scan gives your mechanic a complete picture of what’s happening, so you can fix problems early, avoid breakdowns and drive with confidence.

Vehicle Diagnostics FAQs
How long does a diagnostic check take?
A standard diagnostic scan usually takes 20 – 40 minutes, depending on the complexity of the issue and how many systems need checking. Some faults are straightforward, while others require deeper analysis or road testing to reproduce the problem. If your vehicle has multiple warning lights or intermittent issues, the process may take longer. Your Midas mechanic will give you a timing estimate upfront.
How much does a vehicle diagnostic scan cost?
The cost depends on the type of scan and how complex the issue is. Basic scans are generally quick, while in-depth diagnostics may require more time to interpret codes and test components. At Midas, we always provide upfront pricing before any work begins. If repairs are needed, you’ll receive a clear quote so you can make an informed decision.
Does a diagnostic scan fix the issue?
Not always. A scan identifies the issue by reading fault codes and system data, but a repair may still be required. For example, a code might show a misfire, but the underlying cause could be a spark plug, ignition coil, fuel injector or sensor fault. Our technicians explain what the scan reveals and outline the next steps so you can resolve the issue quickly and confidently.
What if my car shows multiple fault codes?
Multiple fault codes are common and modern cars often log several related errors at once. Some codes are symptoms, while others point to the underlying cause. Our mechanics analyse the full system to determine which codes matter most, how they connect and what needs repairing first. We explain everything before starting any work.
